Hi,
We are using a application which uses port in CLOSE_WAIT Status.
netstat -an|grep 9191
192.168.32.11.9191 192.168.32.11.54562 49152 0 49152 0 CLOSE_WAIT
192.168.32.11.9191 192.168.32.11.54564 49152 0 49152 0 CLOSE_WAIT
192.168.32.11.9191 192.168.32.11.54568 49152 0 49152 0 CLOSE_WAIT
192.168.32.11.9191 192.168.32.11.54576 49152 0 49152 0 CLOSE_WAIT
*.9191 *.* 0 0 49152 0 LISTEN
How can I make this port to LISTEN without rebooting the Application or Server.
I think the server waits 60 seconds (Sol 10 default, while the old RFC standard is 240) for the client application to finally close the connection in CLOSE_WAIT.
That means each CLOSE_WAIT should go away latest after 60 seconds.
The last netstat line says there is already a service process in LISTEN status.
After shutting down the service (especially after a kill -9) you might need to wait a minute until you can start it again.
There are too many CLOSE_WAIT .

telnet taking too long ..
[jsmishr14@now-back:~] telnet localhost 8089
Trying 127.0.0.1...
And we may have to restart the application running on 8089 to bring it to normal. But it keep on coming to CLOSE_WAIT after sometime.
Do we have anything to fix it permanently.?
Try this:
/usr/sbin/ndd -set /dev/tcp tcp_time_wait_interval 10000
This can also be the result - on an oracle server - of the the client server having problems.
Users can close an oracle forms screen with the 'X' at the top right. It stops the owner process, the co-process that is owned by user=oracle on the client server does not disconnect correctly. This is a known bug in oracle 9i for example. jlliagre's ndd solution is a good workaround, if in fact this is oracle. The cure is a software update for your client servers.
The reason I believe this is an oracle problem is the 49152 port - oracle uses this for client connections.
So I would consult Oracle for a solution.
The ndd tuning is a mitigation rather than a solution.
